with inert gas to about 103 Pa. The electric arc in the inert environment was automatically ignited between the tungsten electrode and the water-cooled nozzle by the high frequency initiator. Under the gas... properties of the nanopowders by this method can be easily improved by varying the processing parameters, such as the type of inert gases, the ambient gas pressure, the arc current intensity......
="ChDivSummary" name="ChDivSummary">Double shielded gas tungsten arc welding (GTAW, also known as tungsten inert gas (TIG) welding) of an SUS304 stainless steel with pure inert argon as the inner layer.... The experimental results showed that the inner inert argon gas can successfully prevent the outer layer active gas from contacting and oxidizing the tungsten electrode during the welding process. Active gas......
